Here is our story. We set up a 55 gallon freshwater tank 8 weeks ago. We wanted to cycle the tank using fish. We started with 5 danio's. We have all plastic plants. We are using a Marineland Bio-wheel 350. Feeding using Omega one food. We have had no ammomia, nitrites or nitrates using the API test kit. My wife and I are totally frustrated. Last week we added 4 additiional danio's in hopes of creating ammonia. My wife and I are totally frustrated with either the lack of cycling or more concerning, the green algae bloom that has made the tank very cloudy. Any ideas,questions or comments would greatly be appreciated.
